First let's evaluate f%284%29


f%28x%29=4x-2 Start with the given function.


f%284%29=4%284%29-2 Plug in x=4. In other words, replace each x with 4.


f%284%29=%2B16-2 Multiply 4 and 4 to get 16


f%284%29=14 Now combine like terms


Now let's evaluate g%283%29


g%28x%29=-2x%2B1 Start with the given function.


g%283%29=-2%283%29%2B1 Plug in x=3. In other words, replace each x with 3.


g%283%29=-6%2B1 Multiply -2 and 3 to get -6


g%283%29=-5 Now combine like terms



So

f%284%29%2Fg%283%29=14%2F-5=-5%2F14
